That comes on the heels of Friday's announcement by EDP Renewables North America LLC, which will provide 100 megawatts of wind power from its Arbuckle Mountain Wind Farm to Nebraska's Lincoln Electric System.

Kylah McNabb, renewable energy specialist at the Oklahoma Department of Commerce, said it is exciting to see new Oklahoma wind projects being developed to serve utilities in other states.

She said Oklahoma has not added any new wind generation this year, but there are more than 500 megawatts in announced projects under construction.

Those projects should be operational before the end of next year.

Oklahoma has 3,134 megawatts of installed wind capacity, which is good for sixth in the United States, according to the American Wind Energy Association. The state's wind potential of 516,822 megawatts in the ninth-best in the country, according to the National Renewable Energy Laboratory.

RES Americas is building a wind farm with 75 turbines in Murray and Carter counties. It is expected to be operational by the end of 2014.

All of the new wind farm's power will go to Arkansas Electric Cooperative Corp., which provides electricity for more than 500,000 members of the state's 17 electric distribution cooperatives.
